Someone who uses lol not only too much in a conversation, but is most likely NOT laughing out loud at what was previously said. Not only is this person an abuser of an already retarded term, but they are a liar. Hit them.

Vladimir: I'm really confused with this hw.
Eric: lol
Vladimir: Why is that funny? I really am confused.
Eric: I'm not laughing lol
Vladimir: Why are you using lol then?
Eric: lol
Vladimir: You are a lol abuser and I loathe you, no lol. I will kill you dead.
